You don't have to be able to spawn in order to marry, so that's a non issue.<quoted text>
We've never said that it invalidates a person, just said that SSC's are not equal to heterosexual couples, and ought not to have the same laws supporting it, as if they WERE equal. Reality is that the SSM'ers are seeking to gain legal validation of their broken relationships, as if they WERE the same as the regular couples. And, as per "having" their own children, some are using laboratory processes to "have" these children. More unnatural behavior, to lay claim to "equality".
And there is same sex sex in nature. That's the definition of natural, dummy.
